A flow view for SwiftUI

Flow

---

A layout for placing views in a flow-like arrangement in SwiftUI. A Flow organizes views sequentially, wrapping them onto new lines when the current line is filled. The alignment and spacing between views can be customized. Flow layouts are commonly used to display a set of tags.

Using Flow is similar to using SwiftUI's VStack and HStack layouts/views. Alignment and spacing changes can be animated and since Flow conforms to the Layout protocol you can even animate changing to an entirely different layout type!

Usage

import Flow

struct ContentView: View {
    @State var tags: [Tag]

    var body: some View {
        // Default .topLeading alignment and system spacing.
        Flow { 
            ForEach(tags) { tag in
                TagView(tag)
            }
        }
        // Alignment and spacing specified.
        Flow(alignment: .bottomTrailing, spacing: 10) {
            ForEach(tags) { tag in
                TagView(tag)
            }
        }
    }
}
